The present application 15 a division of my prior ap lication for Letters Patent of.

the United tates for an improvement in soda water fountains, Serial #658,592, filed August 21st, 1923, patented July 1, 1924,No.

An object of the present invention is to providea simple, reliable and conveniently operable operatingmechanism which is particularly well adapted for use in a soda water fountain or like machine for dispensing liquid to control the dispensing means of the machine in such manner that liquid cannot be dispensed by the machine until a suitable coin has been deposited in the machine.

A further object of the invention is to provide a coincontrolled operating mechanism of the character described which cannot be actuated to operate a vending mechanism until a suitable coin has been placed in a coin receiving member of the mechanism.

Other objects and advantages of the in vention will be apparent from the following description, considered in conjunction with the accompanying drawings, forming a part of this application, in which- Figure 1 is a vertical section through a soda water fountain equipped with an operating mechanism embodying the invention.

I J A soda water fountain with which an operating mechanism embodying the present invention is adapted to be used is indicated generally-at 1 and includes a mixing and dispensing apparatus which is located in the upper part of the soda water fountain as My invention is a coin controlled operatdelivery conduit 3, the discharge end'of PATENT oFFIcE- which is located exteriorly of the casing of the soda water fountain. A valve a for controlling the flow of liquid through the delivery conduit 3 is provided with an operating arm 5 which is swingable in a vertical plane. A lever 59 for actuating the operatl-- ing parts of the mixing and dispensing apparatus is pivotally supported adjacent to 9 its outer end on an upstanding bracket arm 61 which is carried upon the casing of the soda water fountain. The lever 59 is swing able in a vertical plane. One of the operating partsof the mixing and dispensing apparatus is the vertically reciprocable rod 57 whichis pivotally attached at its upper end to the lever 59 intermediate the inner ends of the lever 59 and the fulcrum of the latter. Another operating part of the mixing and dispensing apparatus is the vertically reciprocable rod 46 which is urged axially upward by a spring 4i9 ag'ainst a spring finger which is secured to thelever 59 at the inner end of the latter, whereby the inner end'portion of the lever 59 normally will be maintained in upwardlyswung or raised position. When the inner end portion of the lever59 is swung downwardly against the action of-the spring. 49, the operating parts of the mixingand dispensing apparatus will be actuated in suchmanner as to force a quantity of liquid therefrom into the delivery conduit'and when the valve 4 of the delivery conduit isopen, the quantity of liquid entering the delivery conduit will be dis- An operatingmechanism embodying the present inventionaffords actuating the lever 59' and the arm or handle 5 of the valve simultaneously to open the valved, at the time the inner end portion of the lever 59 is swung downwardto operfacilities for ation of the soda water fountain and of the mixing and dispensing apparatus there-i of is described in detail in my aforesaid prior application for patent. It-is thought that no further description herein is necessary in order that the construction and operation of an embodiment of the'present invention may be understood since a practical embodiment of the present invention may be operatively applied to dispensing devices other than that which is indicated at 2 in the drawings, as will be understood from the following description.

A vertically movable operating rod 79 .is pivotally attached adjacent to its upper end to the arm 5 and'bears-at its upper end continuously against the under side of the outer end portion of" the lever 59. "A casing 8l'designed' to house the mechanism for controlling the up and down operation of the rod 79 and to accommodate in its lower part the coin receiving drawer 82 is carried by the casing of the soda water fountain. The rod 79 extends vertically downward from its connection with the valve handle 5 through an opening in the upper part of the casing 81 into the latter and through an opening in a horizontal stop projection 93 which is disposed within'the casing 81. As

best seen, a foot or hand lever 84for actuating the rod 79 extends into the casing 81 through a suitable openingin the front wall of the latter and is pivoted at its inner end,

at 88, to the lower end of the rod 79. The lever 84 is fulcrumed within the casing 81 intermediate of its-length on a fixed horizontal pin 85. A tilt bar 87 is pivoted at 86 to the lever 84 at a point intermediate the pivotal connections at 83 and 85, the tilt bar being freely swingable in a vertical plane. The outer end portion of the tilt bar is formed to provide a head 88 adapted to" receive-and support a'co-in, such as indicated at 8 9," as the coin falls from a coin chute 90, the tilt bar normally being maintained by gravity in horizontal and coin re ceiving' position by reason of being weighted at its inner end, as indicated at 91. The tilt bar 87 is provided intermediate its inner' end and the pivotal connection at 86 with an upwardly and laterally projecting stop lug 92 which is adapted when the inner clear the adjacent end of the stop 93 as the tilt bar swings to horizontal position I when the lever 84 is in normal or inactive position as" indicated by the full lines in Figs. 1 and 3, the lever 84 then being inclined downwardly from its outer end to The inner or. weighted end of the tilt bar will barely its inner end. The inner end of the tilt bar 87 will engage with the under side of the stop projection 93.npon attempted swinging movement of the inner end of the lever 84 upward from inactive position so long as the tilt bar is in substantially horizontal position and the engagement of the stop project-ion with the upper side of the lever 84 will result in the lever 84 being held at that time against such swinging movement from inactive position as would raise the inner end of lever above the level of the stop projection 93. A pull spring 95 eX- tends through a suitable opening in the top of the casing 81 and is connected at one end to the outer end portion of the lever 84 and at its other end to the casing of the soda water fountain, as at 96, the action of the spring 95 being to normally maintain the lever 84 in an inactive position, as indicated by the full lines in Figs. 1 and 3.

From the foregoing description of the various parts of the device, the operation thereofmay be readily understood. A given coin falling into the chute 9O rests upon the head 88. The weight of the coinon the outer end portion of the tilt bar 87 causes the latter to swing downwardly from the "full line position to the intermediate dotted line positionof Figure 3, at which time the stop lug 92 again engages with the upper side of the lever 84. The movement ofthe tilt bar 87 from the full line position to the intermediate dotted line position of Figure 3 is sufiicient to cause the inner end of the tilt bar to clear the adjacent end of the stop 93 but is insufiicient to cause the coin on the head 88 to roll therefrom. The outer end portion of the lever 84 may now be depressed, thus causing an upward movement of the operating rod 7 9 and actuation of the valve handle 5 and the lever 59. When the lever 84 is in the positionindicated by the dotted lines in Figure 3, the tilt bar 87 will assume the nearly vertical position indicated also by dotted lines in Figure 3' and the coin will fall from the head 88 through a delivery tube 94 into the-coin box 82.

From the foregoing, it will be manifest that the lever 84 cannot be swung from in-' active positionto operating position until a coin of a givenweight has been deposited in the chute 90 and rests upon the head at the outer end of the tilt bar 87; Therefore, the dispensing apparatus of the machine with which the operating mechanism is associated cannot be'actuated to cause deliv-- cry of an article which is to be vendeduntil a suitable coin'has been deposited in the coin chute of'the' machine Obviously, myinvention is susceptible of embodiment in forms other than that illustrated in the accompanying drawings and I therefore consider as my own all such modifications and adaptations of the form of the device herein described as fairly fall within the scope of the appended claims.

Having thus described the invention, what I claim is 1. A coin controlled operating mechanism comprising a lever fulcrumed intermediate its ends to swing about a horizontal axis, said lever being adapted for connection at one end with an operating rod, a tilt bar pivotally attached intermediate its ends to said leverat a point intermediate the fulcrum and said one end of the lever, said tilt bar having a coin receivin head at one end thereof, the opposite end portions of said tilt bar being balanced in weight, means for limiting the swinging movement of said tilt bar in respect to said lever, and a stop extending in the path of said tilt bar when the lever is in normal position and the tilt bar is in balanced position, said stopterminating short of the path of said tilt bar when the latter has been vswung from balanced position bythe weight of the coin on said coin receiving head.

2. A coin controlled operating mechanism comprising a lever fulcrumed' intermediate its ends to swing about a horizontal axis, a spring attached to said lever to hold the latter normally in inclined position, an op erating rod pivotally attached to the normally lower end of the lever, a tilt bar pivotally attached intermediate its ends to said lever at a point intermediate its fulcrum and the normally lower end thereof, said tilt bar being adapted to swing about a horizontal axis and normally beingmaintained in substantiallyhorizontal position by gravity, a stop projection on said tilt bar for engaging with the upper sideot the latter for limiting the swinging movement of the tilt bar in respect to said lever said stop projection being carried by said tilt bar between its point of pivotal connection with the lever and one endthereof and said tilt bar being provided atflits other end with a portion adapted to receive a coin and to support the coin thereon until said last named end portion of the tilt bar has been swung to the limit otits downward Vmovement, and a stop located above the the lever is swung upward from normal position.
